The exploit, which requires a modified save file and a copy of Cubic Ninja, reportedly enables the use of homebrew games and applications on Nintendo's handheld. It does not currently enable piracy of commercial games -- a widespread issue that plagued the Nintendo DS throughout its lifespan.
After the exploit was announced, used copies of Cubic Ninja shot up in price on eBay, Amazon, and through other third-party sellers. The North American version of the game currently fetches prices in excess of $40 on Amazon, while several recent eBay auctions have ended at over $30. A similar phenomenon spiked Lumines prices when a homebrew-enabling buffer overflow exploit was discovered for Sony's PSP in 2007.
